Experience..unless your breeding on paper...assuming you still record actual data and breed according to the "actual" performance. If you report the data correctly it will reflect in the EPD's over a period of generations anyway. You may never get the EPD's to "adjust" completely to reflect the epitomy of EPD numbers or what the animal "should" be comparing with based on EPD averages, but don't let numbers determine which animal is good in your herd and which is not.
Thanks for your input! The EPDs were a new experience to me when I started back in 2002. And I tended to put too much emphasis on them at first.
We had participated in the old TPR program for about 20 years. The "in-herd" data that we got from that was pretty useful.
But I've seen some things that have made me seriously question the real value of EPDs, except where there is considerable data to back it up, as in widely used bulls.
An example is the P606 bull. He was initially being marketed as a low BW, calving ease bull, but as his use has widened, his BW EPD has skyrocketed while his YW EPD has also receded by about 20 lb. No doubt he's still a very good bull, but his EPDs have changed.
Here is the press release for the next Hereford 101 online:
********************************
Hereford 101: So You Think You Know EPDs
The next online Hereford 101 will be Oct. 20 at 7 p.m. CDT. Dan Moser, Kansas State University associate professor, will join Jack Ward, AHA chief operating officer and director of breed improvement, to discuss why EPDs are more important than actual individual performance.
Participants will be encouraged to submit questions, either by calling in or through the online "chat."
In order to view the video, your computer needs to have a broadband connection to the Internet. Dial up Internet will allow you to participate, but will only facilitate the audio portion of the Webinar.
If you go to LiveAuctions.tv, you will see an item in the calendar (list of auctions) for Hereford 101. Click on it and you will be prompted to enter a user name and password.

Now this is one that I definitely intend to tune in on and watch with interest!
